Basic Principle of NDIR Gas Detection - Heimann Sensor

IR radiation with µm is not absorbed by either CO2 or other common gases in the atmosphere and is transmitted without loss to the detector. Therefore, it is well suited as reference with no absorption. IR radiation with µm wavelength is only absorbed by CO2 molecules and by no other gases in the atmosphere. This means, that the degree of radiation reduction on that channel depends ...

CO₂ sensor - Infineon Technologies

The PAS principle works as follows. Pulses of light from an infrared source pass through an optical filter tuned specifically to the CO 2 absorption wavelength (λ= µm). The CO 2 molecules inside the measurement chamber absorb the filtered light, causing the molecules to shake and generate a pressure wave with each pulse. This is called ...

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR …

What is a CO2 Sensor? | How does it work? - CALT Sensor

How does it Work? An NDIR CO 2 sensor has 4 important parts, the chamber, gas inlet and outlet valve, infrared(IR) lamp, and an IR detector. One end of the chamber has an IR lamp that produces IR rays within the absorption band of CO 2 molecules. At the opposite end of the chamber, an IR detector is fixed to measure the intensity of the emitted rays. The inlet and outlet valves control the ...
